Title: Eddy-current flaw detecting method for steel pipe
Inventor: KAMIMURA SHIGENORI
IPC: G01N27/90
Filed: 1994-07-27
Abstract: PURPOSE:To increase a sensing force for a flaw on the inner surface by determining the DC magnetic suturation level to such a degree that the magnetic permeability mu maximizes on a model material which is equipped with an inner surface flaw to a degree as to be sensed, subjecting a test specimen to a DC magnetization to this level determined, and thereby maximizing the impedance change of a test coil. CONSTITUTION:The impedance change of a test coil is sensed in the process that the DC magnetic suturation level of a model material is varied by a DC magnetic saturating coil, and it is judged that the magnetic permeability muhas maximized when the impedance change is maximum. If for example the saturation level where the permeability mu of a test specimen is approx. one is assumed as 100%, setting to the saturation level 10% causes the permeability muaround an inner surface flaw of the test specimen to maximize, This widens the part which generates mu>100 around the flaw and the amount of leaking lines of magnetic flux in this part increases, which heightens the sensing force of the test coil. That is, increase in the leaking magnetic flux around the flaw causes the impedance change of the test coil to maximize around the defect, and it is possible to detect flaw with a high S/N ratio.

Title: Method of cooling and cleaning high temperature smoke gas contaminated with dusts and containing dioxin and other toxin
Inventor: BUINFURIITO HEEGUNERU
IPC: C21C5/56
Filed: 1993-06-24
Abstract: The present invention pertains to a process for cooling and purifying hot, dust-laden flue gases enriched with dioxins and other toxic components from a melting vessel, e.g., an arc furnace. Both the flue gases A, B generated during charging and those generated during the melting operation are collected, and the toxic components are removed in two ways. The flue gases A collected in the exhaust hoods 2 are fed into the filter 6, while previously blowing an additive 12, on which the toxic components settle before reaching the filter bags, into the flue gas stream A. The hot flue gases B drawn off directly from the arc furnace 1 are introduced into a combustion chamber 3 after passing through a water-cooled section 4, and are subjected to afterburning in the combustion chamber 3 to remove the toxic pollutants. These gases are then intermediately cooled in a second, water-cooled section 5, further cooled by adding more additional cold air A, and fed into the filter 7. The contaminated dust E is charged again into the arc furnace 1.
